Bacteriophages: Nature's Precision Antibacterial Agents
Pathogenic microorganisms are ubiquitous across livestock, poultry, and aquaculture production systems, posing persistent infection threats. In natural ecosystems, however, bacteriophages have co-evolved as natural bacterial antagonists for billions of years, maintaining ecological balance by selectively lysing host bacteria.
Unlike chemical broad-spectrum antibiotics, bacteriophages recognize distinct surface structures (such as LPS, flagellar proteins, or capsular polysaccharides) on pathogenic strains. Once attached, a lytic phage injects its DNA, hijacks host machinery to replicate logarithmically, and expresses endolysins to rupture the bacterial cell wall, releasing hundreds of progeny phages to clear surrounding pathogens.
- Zero drug residue: Composed purely of natural nucleic acids and proteins, leaving no chemical footprint.
- High specificity: Completely harmless to beneficial commensal flora such as Lactobacillus and Bifidobacterium.
- Overcomes MDR pathogens: Highly effective against bacteria resistant to carbapenems, cephalosporins, and fluoroquinolones.
New-Line Bio's R&D Center utilizes advanced biobanking and automated fermentation technology to formulate stable, broad-host-range phage cocktails that address the most pressing clinical bacterial challenges in agriculture.
